BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to methods and apparatus that include the acquisition of data, analysis of the collected data, and transmission of the collected data and/or analysis of the collected data to a destination by means known to a practitioner of ordinary skill in the art. More particularly, the present invention relates to methods and apparatuses that include collecting analog or digital sensor data onboard an aircraft, analyzing said data in real-time, and transmitting the data and/or analysis of the data to a destination including a portable storage device such as a portable computer or electronic flight bag (EFB) by means including wireless transmission. The application of this invention includes sensor data gathered from aircraft used in field of avionics such as aircraft or other data collection/generating devices such as medical apparatus, IR (infra-red) heat sensing sensors, or other devices whereas the invention is used to pre-process or post-process the collected information.

2. General Background of the Invention

In the normal operation of aircraft, pilots are typically required to carry flight bags that contain reference material such as aircraft operating manuals, flight-crew operating manuals, and navigational charts. In order to promote efficiency in flight management tasks and reduce the usage of paper, electronic information management devices such as EFBs have been employed by flight crews. Such EFBs allow for use of various applications including static applications such as document viewers, flight crew operating manuals, electronic approach charts, and multifunctional displays for systems such as navigational systems and air traffic control instructions. Furthermore, EFBs can include various means of data transmission including memory stick transfer and wireless connectivity.

Also, aircraft in general have onboard systems which communicate in real-time with systems on the ground during the course of a flight. Methods and apparatus directed towards such systems have patented. For example, U.S. Pat. No. 7,835,734 to Eckert et al. discloses an avionics system including a wireless router located on an aircraft and configured to transceive wireless signals; and a processing unit located in the aircraft and configured to supply the wireless router with configuration parameters after determining it is time to connect to a ground network, the configuration parameters based on the location of the aircraft; wherein the wireless router uses the configuration parameters to establish a wireless connection with the ground network and route data from at least one client application on the aircraft to at least one ground application server.

In view of the current state of art, current technologies related to electronic flight bags and real-time communications systems have yet to address the need for systems and apparatus that can efficiently collect, analyze, and transmit data recorded by an aircraft's sensors or other such sensors carried aboard or affixed to the aircraft. Such systems could aid commercial aircraft carriers in improving efficiency in delivery of their services to customers as applied to concerns or issues that include flight costs or flight crew performance. Also, such systems could provide vital data to administrative agencies regulating the field of avionics for various investigatory concerns such as efficiently determining the cause of an aircraft failure.

BRIEF SUMMARY OF THE INVENTION

The disclosed invention addresses what the current state of the art has yet to address.

The present invention relates to methods and apparatus that include the automatic acquisition of data, analysis of the collected data, and preferably automatic wireless transmission of the collected data and/or analysis of the collected data to a destination for storage or analysis, for example, from an aircraft by automatically transmitting the data to a portable device on the aircraft which is carried onto the aircraft by the pilot or other crew member and is removed by the pilot or other crew member when he exits the aircraft. More particularly, the present invention relates to methods and apparatus that include automatically collecting analog or digital sensor data onboard an aircraft, analyzing said data in real-time, and automatically transmitting the data and/or analysis of the data to a destination including a portable storage device such as a portable computer or electronic flight bag (EFB) by means including wireless transmission.

It is sometimes best to encrypt data first, then automatically transmit to a device that will leave with the pilot. Preferably the data is automatically wirelessly transmitted to a portable storage device in the airplane, but one could use cat-5 cable or other wire to connect to a computer or computer-like device.

Preferably one uses a powered device that can capture the data (a device with logic platform versus a simple storage device, such as an SD card), whether the data comes wirelessly or through a wire, and the device enters the aircraft with the pilot and leaves with the pilot.

The present invention includes automatically moving a consolidated stream of data to a device that contains logic (preferably a computer), preferably in real time or near real time. Preferably, the computer has software that analyzes the data and can send messages to remote locations or simply let those in the aircraft know that there is an issue (the computer can be programmed to detect some issues that normal flight equipment might not).

Two recent events have occurred in FAA rules to make the present invention possible:

(1) wifi can now be on aircraft:

(2) electronic flight bags are now allowed in the cockpit.

The hardware used in the collection, processing and transmission over wifi to the EFB or other portable electronic device can reside in the MFDAU (preferably), QAR, or any such external device that is integrated into the system.

Preferably, the data is automatically wirelessly transmitted to the EFB or other portable electronic device carried by the pilot or other crew member onto the aircraft, then automatically wirelessly downloaded from the EFB or other portable electronic device after the EFB or other portable electronic device is removed from the aircraft by the pilot or other crew member, typically when the portable electronic device connects to a network after it is removed from the aircraft. While the data could be downloaded via for example a Cat5 cable after the portable electronic device leaves the aircraft, wireless transmission is preferred.

The storage medium is preferably a Secure Digital (SD) memory card. The means of transmission can be transferring multiple external component data to other storage means such as an EFB, a computer, medical, or auxiliary equipment. In a preferred embodiment, the QAR preferably receives data from the CV2R Ethernet Feed, the Ethernet Vibration Feed, and the MFDAU Data Feed. In a more preferred embodiment, the MFDAU preferably both sends and receives data to and from the CV2R Ethernet Feed, the Ethernet Vibration Feed, AirInc 429, and auxiliary inputs such as analog signaling devices. The MFDAU feed preferably includes airframe, engine, and component data via a direct interface to digital ARINC (including but not limited to ARINC 717 and 429 data), serial (including but not limited to RS232, RS485) and analog data streams as well as aircraft state data as provided by internal or external gyros and accelerometers. The collected data preferably provides detailed aircraft state, including pitch, roll, G forces, vertical speeds, detailed engine operating parameters (i.e., turbine speeds, oil pressure & temperatures) and primary aircraft system parameters (rotor speeds, transmission and gearbox oil pressures and temperatures). Also preferably included in the data stream delivered to the MFDAU or QAR is the state of caution and warning lights and the position/state of significant system switches in the aircraft (i.e., landing gear switch and gear position indicator lights). Detailed GPS component data streams are preferably included in the acquired data. Once received, the MFDAU or QAR board preferably directs a composite data stream to the EFB and/or through the USB 3.0 Adapter to hard memory. The composite data stream is preferably transmitted from the MFDAU or QAR to the EFB wirelessly. This preferred embodiment preferably also includes light indicators for the MFDAU QAR SD Card Write Status and WiFi connection status as well as a button for opening and closing a door. A preferred apparatus is a NORTH QAR-3W Quick Access Recorder or MFDAU with a means for wireless transmission of data, both of which can be similar to NORTH QAR-3W Quick Access Recorder or MFDAU currently commercially available from North Flight Data Systems, LLC.

A MFDAU is a multi-function data acquisition unit. It typically includes at least the following: Digital and analog data receivers, an internal attitude and heading reference system, and other such electronic devices with which to acquire information from various devices. When used in the present invention, it preferably also includes a logic platform and operating system that facilitates the acquisition of data, hosts firmware and software to enable it to either direct the raw data or to manage acquired data and to perform analyses of the data, manipulate the data, encrypt the data, and classify the data as to type, origin, and protocol for processing the data.

The MFDAU of the present invention with wireless capability could be used in place of the QAR in FIG. 2.

FIG. 3 is a schematic view of the process for transferring data from the QAR to the EFB. In the preferred embodiment, the QAR board attempts to and establishes a secure connection with the EFB wirelessly. The QAR may also seek auxiliary wireless signals to establish a secure connection. In preparation for receiving data, the EFB may create files to incorporate the transmitted data within. Once a secure connection has been established, the QAR streams the data to the EFB. When the aircraft has shut down, the QAR may switch to a backup/cap power and may send an end-of-file message prior to a backup power timer expiring. Once the data is received from the QAR, the EFB may include means of distributing the data, encrypting the data, or writing the data to the previously created files. Once the data is written to files, the EFB may close the files and terminate the wireless connection with the QAR. In FIG. 3, one could substitute a MFDAU of the present invention with wireless capability for the QAR.

The present invention includes methods and apparatus directed to collecting internal and external analog and digital sensor data; analyzing the sensor data and transmitting of said data to a portable storage device.

In one embodiment of the present invention, the method or apparatus includes a process of collecting data. The data preferably includes internal and external data that may further include data acquired from an analog or digital sensor. Sensor data also includes aircraft, state, component data, voice, video, and vibration information. The data recording is preferably combined into a combined data stream. The combined data stream is preferably transferred to either a fixed or portable onboard storage device via wireless transmission. The combined data stream preferably includes data from similar and dissimilar devices (i.e. aircraft data video and still camera images such as jpeg, mpeg formats; forward infra-red camera images, radioactive particle sensor data, medical device data).

In another embodiment of the present invention, the method or apparatus includes a process of analyzing data. Analysis of such data may include analysis of aircraft sensor data in a virtual live basis in flight with Flight Operational Quality Assurance (FOQA). The analysis may also include an analysis of aircraft sensor data with vibration software that preferably compares the composite data stream to either a predetermined set of events criteria or historical data trends providing Maintenance Operation Quality Assurance (MOQA) system or subsystem health.

In another embodiment of the present invention, the method or apparatus includes transmitting an alert with an exceedance message via a cellular or satellite data conduit after processing the sensor data analysis. This element differs from downloading raw aircraft data wirelessly in that the sensor data has been processed prior to transmission.

In another embodiment of the present invention, the method or apparatus includes transmitting the aircraft sensor data to a crash hardened device installed onboard the aircraft by wireless means.

In another embodiment of the present invention, the method includes combining hardware and software into an apparatus that can be carried, wherein the apparatus wirelessly collects, encrypts, provides for critical near real time processing, and packages data for off load to a corporate data infrastructure for long time processing and preservation. This embodiment of the invention may be further defined to include a process of removing a portable or quasi portable device that has acquired data from onboard wireless devices from an aircraft then acquiring a wired or wireless connection (to the internet or possibly a company's/entity's intranet) and sending that composite data via that wireless connection/conduit. A process of encrypting all collected data and delivering either encrypted or non-encrypted data is a preferable part of this process. The process of taking to the composite data stream, breaking it up and sending it to either one or multiple locations or applications which may or may not act independently. (i.e., send aircraft data to FOQA app, medical data to hospital or doctor, video data to video or motion picture platform, thermal images to law enforcement entities, radioactive readings to an engineering firm). This process is meant to cover the acquisition of dissimilar data via onboard wireless and the administration and distribution of the data from a portable or quasi portable computer and/or electronic device which contains logic.

In another embodiment of the present invention, the method and apparatus includes an avionics data acquisition and recording system. Such system preferably provides an ability to collect wired and wireless sensor data and to deliver a composite data stream through a wireless router (such as 802.11n or 802.1AC) to a portable or quasi portable device that contains logic. The preferred system function would be to have one device mounted in the aircraft that collects: cockpit voice and video from a CV2R device, aircraft flight data (i.e., engine, airframe, and component generated data); aircraft vibration data via airframe mounted sensors or other vibration acquisition components, and external devices data via wi-fi connection (i.e., heart monitor). Once the data is collected by for example either a NORTH QAR-3W Quick Access Recorder or MFDAU, it preferably distributes/writes each primary data stream to an appropriate SD card within the QAR or MFDAU and combines all data source information and transmits it to a portable computer (i.e., EFB, tablet, semi fixed computer device, possibly in a permanently mounted docking station) via a wi-fi transmission.

When the system initially boots up the QAR-3W wifi or MDFAU wifi preferably looks for a receiving device. Each receiving device preferably has been programmed with the appropriate router address and WPA password. The NORTH software/app is preferably set to run when the device is powered up and when the EFB recognizes the QAR wifi or MFDAU wifi and opens a connection to write live stream of data to the EFB memory. When this link is established a “Blue” LED on the QAR or MDFAU preferably illuminates indicating a positive connection and the NORTH app preferably places a “Blue Light” on the tray at the bottom of the EFB screen to preferably indicate positive connection. The QAR (when it is the wifi transmitter—otherwise the MFDAU detects this connection) preferably sends a “message” to the MFDAU which in turn sends a message/flips a bit, which illuminates a light on the system A, V, D, R annunciator (and may turn the letter Blue) to indicate to the pilot that the system is connected and recording via wifi to the EFB.

As the composite data stream is received, the NORTH app preferably takes the data and applies 128 bit encryption as it writes the data to the computer's memory. The recorded data is preferably made available to other software programs the customer wishes to run. The NORTH app preferably monitors the data stream and connection. If the connection is lost, the NORTH app preferably tries to re-establish the connection. If the wifi connection remains intact but the data ceases to flow, the NORTH app preferably initiates the shutdown and closing of files.

While the live data feed is being received by the EFB, a customer can preferably run a live data analysis programs. This may include but not limited to FOQA analysis, and vibration data analysis.

When the aircraft is shut down and power is removed from the NORTH Flight Data System, the battery and/or capacitors preferably provide power to perform the following function: the CV2R will preferably continue to run and power the video camera for one (1) minute. It will preferably record/send data from all 6 channels of audio and one channel of video to: an internal CV2R compact flash memory; a QAR-3W for writing to the QAR “CV2R” SD card; and QAR WiFi router or MFDAU wifi router for transmission to the EFB device. The MFDAU will preferably continue to send any available sensor data to the QAR-3W for one (1) minute and continue to send power (POE) to the QAR for approximately 30 seconds after cessation of data feed to facilitate the closing of the “MFDAU” SD card data file. The QAR-3W will preferably receive its primary power from the MFDAU via power of Ethernet (POE) and write any received data to the appropriate SD card and continue to transmit that composite data stream over the wifi router (unless the MFDAU has the wifi router) as long as it receives that MFDAU power. Upon cessation of the MFDAU POE the internal QAR-3W battery or capacitor will preferably provide power for the closing of files on all SD cards and preferably send an electronic message to the EFB via wifi to close the files on the EFB (alternatively, the MFDAU sends this electronic message if it is making wifi contact with the EFB). When the EFB returns a message that the files have been closed properly, the QAR (or MFDAU) will preferably terminate the wifi connection and shutdown.

After the shutdown process is completed the NORTH EFB app will preferably provide a written message to EFB to confirm a successful shutdown or note an error has occurred. If the EFB loses power by either having ship's power removed from the “docking station” or other source, the NORTH app will preferably close the received data files under the EFB internal battery power. If the EFB or such device has sensed the internal battery may not have sufficient power to continue operation (i.e., low battery alert), the NORTH app will preferably initiate the proper closing of files on the EFB.

If there is a data feed interruption for more than 15 seconds sensed by the EFB (either by the lack of data or a break in the wifi connection), the NORTH app will preferably initiate the closing of previously received data files. If the wifi link is lost, the QAR-3w and/or the MFDAU and the EFB via the NORTH app will preferably try to re-establish the link for a period of one (1) minute. When the wifi link is lost, the blue LED light on the QAR will preferably turn red and the annunciator light will either turn off or turn amber in color.

EFB/Tablet Collection and Processing:

An embodiment of the invention includes placing the computing device or EFB in the aircraft and allowing the computing device or EFB to operate on its own battery power (physical security of the device to be determined by aircraft pilot/operator).

Another embodiment of the invention includes mounting the computing device or EFB in the aircraft via a docking station which has been permanently affixed to the airframe.

Another embodiment of the invention includes a display being an integral part of the computing device or EFB, which is considered “carry on equipment”.

Another embodiment of the invention includes a display for the computing device or EFB that can be considered “Loose carry on equipment” to be secured at the discretion of the pilot/operator.

When an aircraft is initially powered up, the recorder (QAR and/or MFDAU) preferably goes through a system check and the WiFi router preferably broadcasts a Service Set Identifier (SSID) for an EFB receiving device to “see”. If necessary the QAR preferably stores accumulated data from the MFDAU, CV2R and Vibration acquisition units and “buffers” that data until the WiFi router is activated and can make a positive connection with the EFB. Upon establishing a positive connection to the EFB, the QAR (or MFDAU) preferably transmits all stored/buffered data and initiates the continuous flow of received data. If for some reason (regulatory or otherwise) the WiFi router must be disabled (possibly during takeoff or approach/landing) the QAR and/or MFDAU will preferably store/buffer the collected data and upon reactivation of the WiFi router and/or connection the stored data will be sent to the EFB by the QAR or MFDAU.

When an EFB is identified by the QAR router or MFDAU router, the EFB and QAR router or MFDAU router preferably conduct a security check via a shared security key encryption. When a positive connection is made, a signal is preferably sent to the QAR to illuminate the “Blue” WiFi connection LED light on the QAR. Simultaneously, a signal will be preferably sent to the optional panel mounted Annunciator to indicate positive connection (this can be by either turning a segment light on; the segment light can be preferably illuminated in Blue and when a connection is lost it can either turn off or alternatively turn amber). When the MFDAU is used for wifi connection to the EFB, then the blue wifi connection LED could be on the MFDAU.

Upon the acquisition of a positive WiFi connection, the EFB preferably creates at least four (4) primary files (MFDAU, Voice, Video. and Vibration) in which to store the received data. The EFB software will preferably “listen” for auxiliary data streams (e.g., medical equipment, Wx radar data) and preferably will create a file to capture that data if the stream is present.

The EFB will preferably contain a governing application which drives the logic for WiFi connection, security, file structure, and data processing including the option to apply high level encryption to a specified data stream. The application will preferably have a set up function that will store security settings and customer driven options within nonvolatile memory. Alternatively, the encryption can be done by the MFDAU or QAR, whichever connects via wifi to the EFB.

When the data stream(s) are received by the EFB, the EFB will preferably encrypt the data (if selected by the customer) prior to storing the data in the designated file. All encrypted files preferably include individual passwords associated with them to ensure that only authorized users can read that particular data.

During aircraft operation (based upon customer selections) a data stream can be preferably accessed by other applications running on the same EFB which display, analyze and interact with customer commands (e.g., FOQA, Vibration Analysis, medical charting software).

When the flight is complete and the aircraft is shut down, the EFB application preferably closes the files.

Preferred internal power source is to be by means of either: a. Capacitor; b. Lithium battery containing under 25 g of lithium. Processing Capability: 1. The QAR or MFDAU board should run on a standard Linux platform 2. QAR or MFDAU Board should be capable of processing a minimum flow needed to handle the aggregate flow from all input sources, including:

-   -   a. 3 Mbit/s data from the MFDAU;     -   b. 8 hours of recordings from the CV2R;     -   c. 10 Mbit/s data from the vibration inputs;     -   d. 3 Mbit/s data and messages from the medical or auxiliary         computer sources (up to for example at least 3 auxiliary         devices).         3. QAR or MFDAU Board should be able to apply a continuous high         level encryption of all data streams.         4. QAR or MFDAU Board should be capable of maintaining the         sorting of individual data streams so they may be easily         separated from the composite data stream.         5. QAR or MFDAU Board should have the capability to accept and         execute new firmware changes received through the 802.11         wireless connection from an external device (this could include         that update being received from a satellite communications         (satcom) input).         6. The QAR or MFDAU Board should have the ability to sense brief         wifi interruptions, identify where the break was in the         consolidated data stream and be able to reestablish connectivity         with the EFB and resume data transmission at the point of         interruption (i.e., go back in SSD memory and retransmit data).         7. The QAR-3W should maintain the existing shutdown logic using         the button located between SD Cards. I.e., door open initiates         SD Card close files shutdown process. There could be a different         methodology for shutdown of wifi and EFB stream in cases where         the door may be opened by mistake or even on purpose where a         customer wants to retrieve the SD Card data early but valuable         data is still being received via wifi from medical or other         external devices that should continue to record on the EFB. Such         a methodology could include logic from the internal system         computing platform that will continue to direct live data inputs         to the EFB until such time that total power to the system has         been removed and the EFB has received instructions to perform         the file closing protocols.         Wi-Fi         1. The wifi chip set should be 802.11n or better with a         throughput rate of at least 22 Mbit/s.         2. The wifi capability should be capable of being upgraded to         802.11 ac without a change to firmware.         3. The wifi chip should employ a WPA security routine.         4. The wifi feature should be able to connect to numerous         external devices (e.g., a maximum of 5) with differing         passwords.         5. The wifi feature should be capable of communicating with the         QAR “Connect” blue light indicating positive connection to an         approved device (EFB).

The wifi and encryption can be anywhere on aircraft. Preferably, the wifi capability and encryption can be in either the QCR (quick communications recorder) or the MFDAU.

The logic platform can reside in the MFDAU as shown in FIG. 4, or QAR as shown in FIG. 1. Encryption can take place, for example, in the MFDAU, QAR, or in EFB as shown in FIG. 2, or in a smart phone.

The present invention contemplates moving more data than just what has been heretofore stored on an SD card in a MFDAU, CV2R, and/or vibration monitoring device. The additional data can include for example, medical data, and weather data.
